rwc

This is just a simple version of GNU/wc command clone, written in Rust.
For rust beginners, feel free to look this project for practice :)
(Using Clap-v4)

Features

What I had archived are as follows:

Support for reading multiple files and calculating the result in parrllel
Pretty tabled output
Colorful progress bar for reading files (It is useful when reading large file)
Completions for common shells (Look here for more information)

Note:
It is super faster and prettier than wc command when reading a large of big files. (Thanks to rayon)
But it may be slower when reading a small numbers of small files due to time spending for runtime building.

For the Chinese, you could view my blog about using clap-rs to write this project
